Membrane Filters

Supplier: Sartorius

Cellulose nitrate hydrophilic, gridded membrane filters for colony counting, particle testing and microscopy, with outstanding recovery rates for microorganisms.

Supplier: Sartorius

PES membrane filters are hydrophilic, have high flow rates thanks to the symmetric structure, have a low non-specific protein adsorption and are chemically resistant over a pH range of 1 to 14. They are recommended for the filtration of aqueous solutions as well for the protein filtration. Furthermore, the low level of extractables makes them suitable for environmental analysis.

Supplier: Cytiva (Formerly Pall Lab)

Good prefilter made from PP/PE for heavily particulateladen and viscous fluids. Can be used as separators between stacked discs in a single filter holder during serial filtration.

Supplier: Sartorius

These cellulose nitrate membranes are suitable for air monitoring.

Supplier: Sartorius

Non sterile membrane filters for colony counting, particle testing, microscopy and sterility testing. The membrane filters are made of cellulose nitrate (cellulose ester).

Supplier: Sartorius

Cellulose nitrate hydrophilic membrane filters. For sample pretreatment, particle testing and chemotaxis.

Supplier: Cytiva (Formerly Pall Lab)

Naturally hydrophilic highly versatile laboratory membrane filter.

Supplier: Merck

These PES white membrane filters provides ultrafast filtration of tissue culture media, additives, buffers and other aqueous solutions. This high throughput, low protein-binding membrane is also used in many of our ready-to-use sterile filtration devices.

Supplier: Merck

Ultrafiltration cut disc membranes are available in Ultracel® regenerated cellulose and Biomax® polyethersulvone (PES).

Supplier: Spectrum Laboratories

These woven filters are constructed of individual strands woven into a mesh screen, characterised by precise mesh openings, percent open area and mesh thickness. Available in five material types with different physical, chemical and thermal characteristics to select from depending on your application. Available in discs or square sheets.

Supplier: Merck

These PTFE white hydrophilic membrane compatible with all commonly used HPLC solvents. The membrane undergoes a special treatment process to remove any residual extractables, to provide clearer analysis results. They are widely used for HPLC mobile phase filtration, clarifying acids, bases and dilute protein solutions and isolation of RNA.

Supplier: Merck

Ultrafiltration cut disc membranes are available in Ultracel® regenerated cellulose and Biomax® polyethersulvone (PES).

Supplier: Merck

Hydrophobic edge membranes are standard MF-type filters with edges rendered hydrophobic to 3 or 6 mm widths. In antibiotic and bacteriostatic drug sterility testing by membrane filter method, the 6 mm wide non-wetting edge prevents drug intrusion under holder sealing rim.

Supplier: Merck

Cellulose support pads are used to reinforce filters in monitors for contamination analysis. When saturated with growth medium, they can also be used for culturing microorganisms on membranes.

Supplier: Sartorius

Regenerated cellulose hydrophilic membrane filters. For filtration of organic solvents. Suitable for particle removal from aqueous solutions and solvents. Low adsorption.

Supplier: Sartorius

These sterile cellulose nitrate and PES Microsart® e.motion membrane filters can be used for colony counting, particle testing and microscopy. They are specifically designed for use in the Microsart® e.motion dispenser.
